4. Calculate the standard deviation for the following data set: Foundations of Technology Engineering byDesi OITEEA . . Data Set = 4, 14, 6, 2, 7, 12 217 ,
Answer:
[tex]\sigma_x = 5.68[/tex]
Explanation:
Given
[tex]x = 4, 14, 6, 2, 7, 12 2,17[/tex]
Required
The standard deviation
First, calculate the mean
[tex]\bar x =\frac{\sum x}{n}[/tex]
So, we have:
[tex]\bar x = \frac{4+ 14+ 6+ 2+ 7+ 12 +2+17}{8}[/tex]
[tex]\bar x = \frac{64}{8}[/tex]
[tex]\bar x = 8[/tex]
The standard deviation is:
[tex]\sigma_x = \sqrt{\frac{\sum(x - \bar x)^2}{n-1}}[/tex]
So, we have:
[tex]\sigma_x = \sqrt{\frac{(4 - 8)^2+ (14 - 8)^2+ (6 - 8)^2+ (2 - 8)^2+ (7 - 8)^2+ (12 - 8)^2+ (2 - 8)^2+ (17 - 8)^2}{8-1}}[/tex]
[tex]\sigma_x = \sqrt{\frac{226}{7}}[/tex]
[tex]\sigma_x = \sqrt{32.2857}[/tex]
[tex]\sigma_x = 5.68[/tex]

A host is on the 192.168.146.0 network that has a subnet mask of 255.255.255.0. The binary value of the host portion is 11010101. What is the decimal value of the host portion of the address?
Answer:
213
Explanation:
The given parameters are;
The network on which the host is on = 192.168.146.0
The subnet mast = 255.255.255.0
The binary value of the host portion = 11010101
To convert the binary value to decimal value, we proceed by multiplying each of the digits of the binary value by the corresponding power of 2, from the left to right, starting from a power of 0, and sum the result, as follows;
(11010101)₂ = (1×2⁷ + 1×2⁶ + 0×2⁵ + 1×2⁴ + 0×2³ + 1×2² + 0×2¹ + 1×2⁰)₁₀
1×2⁷+1×2⁶+0×2⁵+1×2⁴+0×2³+1×2²+0×2¹+1×2⁰= 128+64+0+16+4+1 = 213
∴ (11010101)₂ = (213)₁₀
The decimal value of 11010101 is 213.

Assume there are two variables, k and m, each already assigned a positive integer value and further assume that k's value is smaller than m's. Write the code necessary to compute the number of pertect squares between k and m. (A perfect square is an integer like 9, 16, 25, 36 that is equal to the square ot another integer (in this case 393, 4*4, 5*5, 6*6 respectively). Assign the number you compute to the variable q. For example, if k and m nad the values 10 and 40 respectively, you would assign 3 to q because between 10 and 40 there are these perfect squares: 16, 25, and 36.
Answer:
Lets us take k, m = 10, 40
q = 0
i = k
while i <= m:
if int(i*0.5)*2 == i:
q += 1
i += 1

You are concerned that if a private key is lost, all documents encrypted using your private key will be inaccessible. Which service should you use to solve this problem
Answer:
Key escrow.
Explanation:
Cyber security can be defined as preventive practice of protecting computers, software programs, electronic devices, networks, servers and data from potential theft, attack, damage, or unauthorized access by using a body of technology, frameworks, processes and network engineers.
In Cyber security, encryption is a form of cryptography and typically involves the process of converting or encoding informations in plaintext into a code, known as a ciphertext.
Typically, an information or data that has been encrypted can only be accessed and deciphered by an authorized user.
Hence, if a private key is lost, all documents encrypted using that private key will be inaccessible to the users. Thus, the service that can be used to solve this problem is a key escrow because the cryptographic (private) keys kept in an escrow system are protected and would not be released to anyone other than the original user (owner).
A key escrow can be defined as a data security method of storing very essential cryptographic keys.
Simply stated, key escrow involves a user entrusting his or her cryptographic key to a third party for storage.
As a standard, each cryptographic key stored or kept in an escrow system are directly linked to the respective users and are encrypted in order to prevent breach, theft or unauthorized access.

Your organization uses the following tape rotation strategy for its backup tapes: The first set of tapes is used for daily backups. At the end of each week, the latest daily backup tape is promoted to the weekly backup tape. At the end of each month, one of the weekly backup tapes is promoted to the monthly backup tape. What kind of backup tape rotation strategy is being used
Answer:
- Grandfather
Explanation:
In the given scenario, the 'grandfather backup rotation strategy' is employed to have the backup of the audiotape files. This is because the entire process is segregated into three distinct sections; daily backup that keeps the track of all the files recorded every day. It is followed by weekly storage of the audio files after the week wraps up in order to save it for future usage. Lastly, 'monthly' media is backed up in order to ensure that no data is left to be backed up that might be required later. This promotes a quicker, easier, yet complete strategy for backing up the desired data files in the systems. Hence, 'grandfather-son-rotation strategy' is the correct answer.
In large organizations, there is a formal business function that includes developing an information policy, planning for data, overseeing logical database design and data dictionary development, and monitoring how information systems specialists and end user groups use data. __________ is responsible for information policy, as well as for data planning, data dictionary development, and monitoring data usage in the firm.
Answer:
Data administration.
Explanation:
Data management is a type of infrastructure service that avails businesses (companies) the ability to store and manage corporate data while providing capabilities for analyzing these data.
A database management system (DBMS) can be defined as a collection of software applications that typically enables computer users to effectively and efficiently create, store, modify, retrieve, centralize and manage data or informations in a database. Thus, it allows computer users to efficiently retrieve and manage their data with an appropriate level of security.
Generally, a database management system (DBMS) acts as an intermediary between the physical data files stored on a computer system and any software application or program.
Hence, a database management system (DBMS) is a system that enables an organization or business firm to centralize data, manage the data efficiently while providing authorized users a significant level of access to the stored data.
Data administration is a strategic process that is typically responsible for establishing information policy, data planning, data dictionary development, and monitoring data usage in the firm.

why is computer virus called destructive program
Answer:
A computer virus is a malicious software program loaded onto a user’s computer without the user’s knowledge and performs malicious actions.
Viruses which are the most commonly-known form of malware and potentially the most destructive. A virus can do anything from erasing the data on a computer to hijacking a computer to attack other systems, send spam, or host and share illegal content.
Explanation:
The term 'computer virus' was first formally defined by Fred Cohen in 1983. Computer viruses never occur naturally because they are always induced by people. Once created and released, however, their diffusion is not directly under human control. After entering a computer, a virus attaches itself to another program in such a way that execution of the host program triggers the action of the virus simultaneously. It can self-replicate, inserting itself onto other programs or files, infecting them in the process. Not all computer viruses are destructive though. However, most of them perform actions that are malicious in nature, such as destroying data. Some viruses wreak havoc as soon as their code is executed, while others lie dormant until a particular event (as programmed) gets initiated, that causes their code to run in the computer. Viruses spread when the software or documents they get attached to are transferred from one computer to another using a network, a disk, file sharing methods, or through infected email attachments. Some viruses use different stealth strategies to avoid their detection from anti-virus software. Some old viruses make sure that the "last modified" date of a host file stays the same when they infect the file.
